http --- HTTP 模块¶
源代码: Lib/http/__init__.py
http 是一个包,它收集了多个用于处理超文本传输协议的模块:
- http.client是一个低层级的 HTTP 协议客户端;对于高层级的 URL 访问请使用- urllib.request
- http.server包含基于- socketserver的基本 HTTP 服务类
- http.cookies包含一些有用来实现通过 cookies 进行状态管理的工具
- http.cookiejar提供了 cookies 的持久化
http 也是一个通过 http.HTTPStatus 枚举定义了一些 HTTP 状态码以及相关联消息的模块
- 
class http.HTTPStatus¶
- 3.5 新版功能. - enum.IntEnum的子类,它定义了组 HTTP 状态码,原理短语以及用英语书写的长描述文本。- 用法: - >>> from http import HTTPStatus >>> HTTPStatus.OK <HTTPStatus.OK: 200> >>> HTTPStatus.OK == 200 True >>> HTTPStatus.OK.value 200 >>> HTTPStatus.OK.phrase 'OK' >>> HTTPStatus.OK.description 'Request fulfilled, document follows' >>> list(HTTPStatus) [<HTTPStatus.CONTINUE: 100>, <HTTPStatus.SWITCHING_PROTOCOLS: 101>, ...] 
HTTP 状态码¶
已支持并且已在 http.HTTPStatus IANA 注册 的状态码有:

为了保持向后兼容性,枚举值也以常量形式出现在 http.client 模块中,。 枚举名等于常量名 (例如 http.HTTPStatus.OK 也可以是 http.client.OK)。
在 3.7 版更改: 添加了 421 MISDIRECTED_REQUEST 状态码。
